Grid elements can be ordered according to your performing and capacity needs.
Configurations range between a minimum of two grid elements to a maximum of
six grid elements. Partially populated configurations contain three, four, or five
grid elements.
For more information on rack configurations, see “Rack configurations” on page
11.
All configurations have the same power, floor planning, hardware, and software
configurations as fully populated systems.
Important: Each grid controller in a system rack is equally connected to each flash
enclosure in the system, regardless of how many elements are in the system.
Components and interconnect
This section lists the components and interconnection options that are supplied
with each IBM FlashSystem A9000R integrated rack.
